Check for user_id and group_id maybe broken

[gittoar]

User-ID: 33
Group-ID: 33

Yes, it is lower than 100 and therefore an issue but due to restrictions via PHP disable_functions the checks don't work via phpsecinfo.com, i.e. "Not Run
Functions required to retrieve group ID not available".

So the SecurityInfo does not check the return-codes/-infos from phpsecinfo.com properly or the implementation differs from phpsecinfo.com. This is confusing and should be corrected and more documented for minimum debugging purpose. Thanks.
